The downcut helix controls chip ejection by pushing material downward, which reduces surface tearout on the top face of the workpiece. This bit carries a 0.25 inch cutter diameter, a 1.5 inch length of cut, and a 3 inch overall length. The 21-degree helix angle and right-hand cutting direction are matched to the demands of clean-edge profiling and slotting work on thermoplastics and composites. Installation is performed by machinists, CNC operators, and skilled routing tradespeople.\u003c\/p\u003e\u003cp\u003eThis bit is suited for routing acrylic, nylon, PVC, polycarbonate, and solid surface materials in fabrication shop and light industrial environments. The downcut geometry makes it particularly effective when a clean top surface finish is the priority, such as when routing laminate-faced panels or clear acrylic sheet. The 1\/4 inch shank diameter fits standard 1\/4 inch router collets used in both CNC spindles and portable routers. The uncoated solid carbide construction handles the abrasive nature of hard plastic stock without the added complexity of coated tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDowncut flute geometry reduces top-surface tearout on hard plastics and composites\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003e21-degree helix angle optimized for acrylic, PVC, polycarbonate, nylon, and solid surfaces\u003c\/li\u003e\n\u003cli\u003eSingle-edge design suits slotting, profiling, and pocket routing passes\u003c\/li\u003e\n\u003cli\u003e1\/4 inch shank fits standard router collets on CNC and portable routing equipment\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no coating delamination risk in high-friction plastic routing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with routers and CNC spindles equipped with a 1\/4 inch collet.

Power down and lock out the spindle before changing tooling. Insert the shank fully into the collet to the manufacturer-recommended engagement depth and tighten the collet nut with the appropriate collet wrench  -  do not use substitute tools. Verify spindle speed and feed rate are appropriate for the specific workpiece material before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Single Edge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Acrylic, Nylon, PVC, Polycarbonate, Solid Surfaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 62-700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ONSRUD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 62-727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67914781950258,"sku":"62-727","price":84.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a313403dff54325599f7e204287a154b_44635829-7775-4d47-a848-5e022a59ac00.jpg?v=1791250996","url":"https:\/\/voomisupply.com\/products\/onsrud-62-727-downcut-spiral-router-bit-0-25-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
